//no way to re-parameter a template a class when in some special scope 
class base(alias D)
{
  alias D!(int) special ;//error,D is not a template class
   //so function like this can't pass complie  
  auto change(T:long)()
  {
    return new special();//for example change devide!int to devide!long
  }
}

class devide(T:int):base!(devide)
//i think maybe because here: devide = devide!(T)
{

}
int main(char[][])
{
 return 0;
}

there are some different?i am not sure 
class A(alias T)
{
}
and
class B(T)
{
}
//i think if there are different,can be solve the question i mentioned

class D(P):A!D   //base class is a type of A!(D),D is a symbol 
{
}
class D(P):B!D  //base class instance is a type of B!(D!(P)) 
{

}
